WINDSHIELD REGULATOR.

- Application filed December 19.y 1924. Serial No. 757.063.

This invention relates to window regulators and especially'lv a window regulator arranged to lift a relatively wide. heavy panel by drawing the same up and thrusting it down. f l l In the prior Simpson application Serial No. 702,753, a window regulator is described and claimed in its broad aspects for accomplishing the purposes here in view. It is the object of the present invention to provide another type of regulator of this type but which is believed -to vbe an improvement over the Simpson invention in that it .has a more positive action and it eliminates completely the cable. l This cable has introduced a number of problems and diiiculties (lne to stretching, etc.

-Ifn the drawings:

Fig. 1 is a cross section through the top of a closed body, showing an inside elevation of the'header and indicating in dotted lines the regulator.

Fig..2 is a section on the line 2 9. of Fig. 1. .n

Fig. 3 is an enlarged elevation of the driving end of the regulator with parts broken away.

Fig. 4 is a section taken 'on the line 4 4 of Fig. 3.

Fig. 5 is a detail of the upper end of the panel, showing the regulator connection.

a designates the roof of the car; b the removable header panel. A window guide c either of felt or rubber, covered with an anti-friction material, is provided in the windshield post, a sliding glass panel e is raised and lowered by the window regulator. This window regulator is provided with a pair of driven gears or wheels f and' g, carried on a pair of supporting plates lz, and z', which are connected by a. spacing Vstrip j. Riveted to each one of these driven gears is a. crankv arm f1 and g1, carrying crank pins f2 and g2, these engage in the loops c secured to the tops of the windshield vpanel and can slide longitudinally of the panel in the said loops.

The driving effort is communicated from a handle m to a spindle n and thence through a coil spring clutch o, to the drivmg pinion g. It is unnecessary to detail this clutch construction, as the clutch per se is old, and for that matter, numerous forms' of clutches could be used for the purpose, the idea being simply that turning effort originatinf.T in thehandle releases the clutch and turns the driving pinion.- while turning effort originating in the `gears and coming through in the reverse direction 'logks the clutch. This is common construction in all window regulators. i

'Fhedriving pinion f7 meshes with a gear reducing set including the larger gear p and the smaller driving pinion 'l'. This driving.r pinion r is a double purpose gear: it meshes with the driven gear f and also with the slidingrack s. This sliding rack at the opposite end meshes with the driven gear g. The interposition of theI double purpose driven speed reducing pinion 'r serves also to reverse the direction of movement be-4 tween the driven gears f and g. This. is a valuable feature as it causes the thrust of the cranks 'on the panel to neutralize each other.

The spiral counterbalancing spring is associated with the drivengear (7. having its inner end anchored to the stud shaft of the gear and its outer en'd to a struck-out lug u in the supporting plate.

The sliding rack is suitably guided in the. turning over channels o and w in the supporting plates. These channels support the sliding rack, which mesheswith the two gears. The cover plates g/ which tit over the gears are provided with bow springs z Jjfor rubbing against the rack to prevent rattling. In order to reduce the friction, the regulator plates have punched out portions 1 to form point contacts between the sliding rack and the plate.; There is considerable speed reduction between the handle and the' driven or lifting gears. This enables the relatively heavy windshield panel to be lifted without a great deal of effort on the part of the operator, although he will have to turn the crank around several times nisnrand the window-is therefore instantly responsive to vany turning effort. Fur-then.,

' gears and joining the two panel'gears for more, the rack cannot break as it/'is fully strong enough to4 take any and all strainsV and never Wear out.

vWhat we claimis:

l. In a. Window regulator, the combination of two horizontally spaced supporting plates, panel pull-up members on each plate and disposed parallel with the plates, and a positive thrust and draft driving connection between the panel pull-up members.

2. In awindow regulator, panel pull-upl -I members horizontally' spaced atwidely -separated points and arranged so asv to operate when in position in the plane of the window v pocket, and a reciprocating positive thrust -anddraft driving connection between Lthe also Ato reverse panel pull-up members.

3. In a Window regulator, a pair ofV panel lifting wheels horizontally spaced at Widely separated points and each arranged for Separate engagement with the panel, and a ositive thrust anddraft connection between thev panel liftin wheels, which is arranged drive the Wheels -at the 4. In a- Window regulator, 'a couple of panel pull-up wheelsf horizontally spaced at widely separated points` and each having a crank .and pin connectionwwith the top of the window panel, and a' positive push-and pull reciprocating driving -connection between thetwo. panel pu1lup wheels..

5.. In. a" window regulator, the combinai tion of af'pair'of panel ylifting. gears at .widely separated horizontal points, each provided with alifting connection l,with the panel, `driving gears lfor one panel lifting communicatingv the driving eort. and reversing the same as to the two .panel lifting i gears.

6. In a window regulator, the combination of a pair of supporting plates spaced horizontally at widely separated points by a spacerbar,panelflifting gears supported oneach plateand having eachj'av separate connection with the panel,f and al horizontally reciprocating sliding rack guided on said plates and connecting the gears for transmitting the driving effort.

7. In awindow regulator, the combination of a pair of supporting plates spaced horizontally at widely separated points by a spacer bar, panel-.lifting gears supported on eachplate and having each a separateconnection With the' panel, a 'horizontally reciprocating sliding rack guided ony said plates and connecting the gears for transmitting the driving eort, and means bear-A ing yi'eldinglyl against the sliding rack to" prevent rattling.

. '65 8. In a window regulator, thef combinationI of a pair of supporting plates provided I with punched out points, panel-lifting gears supported on'the .plates at widely separated points, a l horizontally reciprocating rackguided in said plates on said points, and yielding'means pressing tbe rack against the points.

In testimony whereof we have aliixed our signatures.l l
